pub fn format_variadic(fmt: &str, args: &[Value]) -> Result<String, String>Expand description
Format a MATLAB-style format string with the provided arguments.
This function consumes arguments in column-major order, supports field widths,
precision (including the * form), and honours the usual printf flags for the
subset required by MATLAB builtins. It is intentionally strict: errors are
reported when format specifiers cannot be satisfied by the provided arguments.
